Application filed August 6. 1904. $erial No. 219,769-

To all whom it may concern:

Be it known that I, VERNON E. ROYLE, a citizen of the United States, anda resident of Paterson, in the county of Passaic and State of NewJersey, have invented a new and useful Combined J ig-Saw and Drill, ofwhich the following is a specification.

My invention relates to a combined jig saw and drill and morearticularly to the arrangement of the drill and its driving mech. anismwith respect to the frame of the jig saw whereby the additionaladvantage of a drill is obtained without, to any great extent,increasing the space required for setting up the jig saw and whereby thejig saw frame may be utilized to a very considerable extent as a supportfor the drill and its driving mechanism.

In the accompanying drawings, Figure 1 is a view of the combined saw anddrill in perspective, Fig. 2 is an enlarged vertical section partly inelevation through the base of the machine, and the parts in proximitythereto, Fig. 3 is a view in 'ront elevation showing the foot pedal andthe means for locking it in its various adjustments, Fig. 4 is anenlarged view in detail in elevation of the drill spindle frame and apart of the jig saw frame to which it is attached, Fig. 5 is a front topplan view of the same, Fig. 6 is a view of the same in front elevationshowing the jig saw frame in section, Fig. 7 is a view in detail showingthe manner of adjusting the drill frame with respect to the jig sawframe, and Fig. 8 is an enlarged view in detail showing the means foradjusting the electric motor bodily through space for tightening thedriving belt.

The pedestal which supports the several runnin parts and which is, infact, the pedestal of the jig-saw, is denoted by 1 and terminates at thebottom in an extended base 2 by means of which it is supported in stableadjustment in such position as may be desired.

The top of the pedestal is provided with a curved supporting arm 3 whichfirst recedes from the top of the pedestal 1 and then re turns over thetop of the pedestal somewhat after the manner of the letter G.

In its free end the jig saw 4 is mounted as is usual and reciprocatesthrough a guide 5 depending from the free end of the overhanging arm 8to operate upon work which may be placed upon a table 6, the jig sawbeing driven by means of a vertically sliding head 7 connected by apitman 8 with a crank wheel 9 on the front end of a drive shaft 10mounted in the pedestal 1 near its base. The shaft 10 is also supportedin a standard or bracket 11 by means of a rocking bearing sleeve 12suspended by a pin 13 in the support 11.

On the shaft 10 there is fixed a drive pulley 14 for rotating the shaft10 and hence the crank wheel 9 and the jig saw, the wheel 14 beingclamped to the shaft by means of a suitable set screw 15 extendingthrough its hub into engagement with the shaft. There is also looselymounted on the shaft 10 a pulley 16 having its hub 17 extended along theshaft 10 in op osite directions from the plane of the face of the wheelto give it an extended bearing with the shaft as it forms the idler orloose pulley to receive the belt in the event the motor is continuouslydriven when neither the jig saw or drill are in operation. There is alsoloosely mounted on the shaft 10 a sleeve 18 which extends through theoverhanging bearing 12 and which, while itself mounted directly withinthe overhanging bearing 12, at the same time forms the immediate bearingof the shaft 10 extending therethrough.

On the sleeve 18 there is fixed a drive pul ley 19 for operating thedrill and also a pulley 20 for transmitting the rotary movement of thepulley 19 and sleeve 18 to the drill by means of a-transmitting drivebelt 21 (see Fig. 1). The sleeve 18 is provided with an annular shoulder22 which bears against the inner end of the bearing 12 and so preventsthe said sleeve 18 from an unintentional outwardl-y slidingmovement'along the shaft 10 while the said sleeve so locked againstlongitudinal displacement on the shaft also serves to locate the hub 17of the loose pulley intermediate of the sleeve 18 and the hub of the sawdriving pulley 14 on the shaft 10.

In the present instance I have shown the machine as driven by anelectric motor and this motor is denoted as a whole by 23 and may be ofany well known or approved form. This motor has its shaft 24 providedwith a pulley 25 by means of which motion is imparted to the severalpulleys on the drive shaft 10 through a belt 26 engaged with the pulley25 and adapted to 'be shifted to any one of the three pulleys 14, 16,19, as may be desired and in a manner which will hereinafter beparticularly explained.

The motor 23 is mounted on a table 27 hinged at its inner end to thepedestal 1 by means of a rod 28 (see Figs. 1 and 8) extend- IIO ingthrough the pedestal and through ears 29 on the table 27, it beingunderstood that there is an ear similar to the ear 29 shown in Figs. 1and 8 on the opposite side of thepedestal for receiving the rod 28.

The table 27 which supports the motor 23 may be swung with the motorthereon in a direction away from the shaft to tighten the belt.Provision for this is-made by loeating a screw 30 in a screw threadedboss 31 fixed to the pedestal 1, the rounded head 32 of the screw'beingengaged with the under side of the table and a screw operating wheel 33being fixed to the screw so that it may be easily manipulated to screwit in or out to lower or lift the table 27. It is to be understood thatthe motor 23 is provided with suitable electric connections by means ofwhich it may be connected with a source of electric energy.

The belt 26 leading from the pulley on the motor shaft to the pulleys onthe shaft 10 is shifted to drive either the saw or drill or needle asfollows: A rod 34 is mounted. to slide longitudinally in the pedestal 1and in the top of the bracket 11. On this rod are fixed a pair of arms35, 36, for embracing the opposite edges of the belt 26 and a coilspring 37 is interposed between the arm 36 and the face of the pedestal1, the tension of which is exerted to throw the rod 34 to its outwardlimit with the arms 35, 36, in position to locate the belt 26 on thepulley 19. The said arms 35, 36, with the belt between them, are drawnagainst the tension of the spring to locate the said belt 26 either on.the loose pulley 16 or on the saw driving pulley 14 by means of a footpedal 38 fixed to a rock shaft 39 mounted in the base of the pedestal 1and provided with an uprising arm 40 engagin at its free end an annulargroove 41 in a collar 42 fixed on the end of the rod 34.

The pedal 38 is locked against the tension of the spring 37 in eitherits partially or fully depressed positions by means of a gravity dog 43suspended-from a pin 44 on the top of a bracket 45 uprising from thebase 2. The dog 43 has a nose 46, intermediate of its support and itslower end, under which the pedal 38 may catch when it is desired to holdthe belt on the loose pulley 16, and has a nose 47 at its lower endunder which the pedal may catch when it is desired to hold the belt onthe pulley 14 for driving the saw.

The drive belt 21 which leads from the pul ley 20 to the drill,straddles the curved arm 3, one part of said belt being located on oneside of the arm and another part of the other side of the arm therebymaterially economizing space and centering the strain of the belt withrespect to the arm 3. After extending to a point immediately above thetop of the arm 3, the said belt 21 is guided by means of guide pulleys48, it being understood that there is a pulley similar to the pulley 48shown on Fig. 1, symmetrically arranged with respect to the guide pulley48 and on the opposite side of the arm, the said belt extend ing fromthe guide pulleys 48 forwardly to the fixed. pulley 49 on the drillspindle 50.

The drill spindle 50 is mounted in any well known or approved form in avertically movable tubular holder 51 connected with a counterbalancedlever 52 for moving it toward and away from its work.

My present invention does not relate to the specific structure of thedrill and the means for moving it toward and away from its work but onlyto the means for supporting the drill and its holder with relation tothe overhahging ar1n 3 of the jig saw. This means of support consists ofa G-shaped frame 53, in the free ends of the branches of which the drilland its holder are mounted, the said frame 53 being attached to the sideand top of the overhanging arm 3 as follows Through that part of theframe 53 which is adjacent to the side of the arm 3 there extends a bolt54 for holding the frame 53 securely in position so far as its movementto ward and away fro-m the side of the arm 3 is concerned while thatpart 55 of the base of the frame 53 which overlaps the top of the arm 3is provided with screws 56 and 57 extending through the flange 55 andengaging threads 58 tapped into the top of the arm 3 as shown in Fig. 7.

The screws 57 are of less diameter than the holes through the baseflange 55 of the frame 53 and said holes are provided with interiorscrew threads with which are engaged short screws 59 bearing at theirinner ends against the top of the arm 3. These short screws 59 havekerfs 60 for operating them by inserting a screw driver into theperforation in the base 55 when the screw 57 is removed but do notextend above the top of the flange 55.

Washers 61 are inserted between the heads of the screws-57 and the topsurface of the flange 55 so that the head of the screw 57 may, throughthe medium of the washer 61, press against the top of the flange 55 tohold it firmly to the arm 3.

By adjusting the short screw 59 slightly inwardly or outwardly, theframe 53 may be tilted either bodily sidewise or edgewise to give it theproper position with respect to the arm 3 so as to hold the drillspindle in a perfectly upright position and this may be accomplishedwithout requiring any planing of the arm 3 and so provides for attachingthis drill frame to the jig saw frames already in common use and settingit up in such form as the table 6 Within convenient reach of theoperator at the top of the pedestal 1 and eX- tends out over the motor23 forming, at the same time, an effective dust guard for the motor anda convenient support for retaining the tools, for example, drills ofvarious sizes, where they can be readily selected when desired.

What I claim is 1. The combination with the pedestal, the motorsupported thereon, a saw frame, a drill frame supported on the saw frameand driving mechanism leading from the motor to the drill, of a combinedtool tray and dust guard supported on the pedestal intermediate of themotor and drill.

2. The combination with the pedestal and the G-shaped arm, superposedthereon, for supporting the jig saw, of the G-shaped supplemental framesuperposed on the said arm for holding the drill spindle in position.

3. The combination with the pedestal and the G-shaped arm for supportingthe jig saw, of the G-shaped supplemental frame superposed on the saidarm and means for adjusting the said supplemental frame comprising ashort screw having a screw threaded engagement with a hole in the baseof the frame and a binding screw extending through the short screw andengaged with the said arm.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this 12th day of July 1904.
